## Structure

This tutorial is a modification of [`ray_tracing__simple`](https://github.com/nvpro-samples/vk_raytracing_tutorial_KHR/tree/master/ray_tracing__simple), which is the result of the ray tracing tutorial. 
All following instructions are based on the modification of this project.

Besides the current repository, you will also need to clone or download the following repositories:

* [nvpro_core](https://github.com/nvpro-samples/nvpro_core): The primary framework that all samples depend on.

The directory structure should be looking like:
